My problem is not knowing the effects of modulus in parts of an equation ( in this case linear ) on the parts of the graph. An elaboration will be like y = |bx| + c , whats the effect on the graph compared to y = bx + c and likewise : y = bx + |c| and y = bx + c or even y = b|x| + c compared to the normal y = bx + c. I believe there is a subtle difference. If so what is that because knowing the "relationship" will allow me to solve the problem.(adsbygoogle = window.adsbygoogle || []).push({});

Sorry, i know any genius like Einstein or Newton will have just find out by themselves but not everyone is like them :( My brain can't interpret such complicated -.- or perhaps someone with perseverence...

If possible, explain on this and i will do the question and not just give me the answer. Anyway the question is given below if you are interested.

1. The problem statement, all variables and given/known data

Firstly, i have no idea how to get the image of the graph here. Well, the shape looks like that /\ with the top end linked. y = a - |bx+c|

The follow points are given on the graph : x = -1.5 when y = 4 , x = 0 when y = 3 , x = -1 when y = 3. They both cut the x-axis twice. Find a,b,c and subsequently x-intercepts.

2. Relevant equations

NIL

3. The attempt at a solution

This is "part" of my homework's question but i do not quite understand how modulus affect the graph in various parts of the equation. Therefore, i couldn't attempt the question.

Thanks in advance,

Sharkey
